Dress to kill in this synthetic spider silk outfit

Qmonos is a tough, lightweight artificial spider silk with mass production applications, including everything from car parts to artificial blood vessels.

Spider silk is about four or five times stronger than steel, but it is remarkably lightweight. So, what would it feel like to walk around in a suit woven of the stuff?

Spiber, a startup in northern Japan, is showing off a dress made from synthetic spider silk. The firm is one of several groups looking into how to make and use artificial spider silk, a task that has proven to be very challenging for scientists.

The electric-blue dress was created from a material Spiber calls Qmonos (from kumonosu, or "spider web," in Japanese). The material is extremely strong and more flexible than nylon.

The high-collared cocktail dress, on display at the Roppongi Hills complex in Tokyo, was created to demonstrate the technology behind Qmonos.

The territorial nature of spiders makes them difficult to farm like silkworms. So instead, Spiber developed a technology that uses synthesized genes and coaxes bacteria to produce fibroin, the structural protein in spider silk. Spiber then uses technology it developed to culture the microbes efficiently and weave the fibroin into fabric.

Apart from clothing, Qmonos could potentially be be used to make film, gels, sponges, artificial blood vessels, and nanofibers.

The company, a spinoff from Tokyo's Keio University, has applied for 16 patents on its spider silk know-how. It is also teaming up with auto parts maker Kojima Industries to build a plant that can turn out about 220 pounds of the synthetic silk a month. Spiber hopes to have an initial mass production of 10 tons a year starting in 2015.

"This fabric can be used in various industries, such as automobiles and medicine," Spiber President Kazuhide Sekiyama told The Asahi Shimbun newspaper.

"It is a major first step toward a manufacturing process that does not depend on petroleum."

Robert Sallin, producer of "Star Trek II: The Wrath of Khan," shares his experience working on the film, looks at the future of "Trek," and dishes on whether that was Ricardo Montalban's real chest.

The release of "Star Trek Into Darkness" has not only spurred interest in the "Trek" world in general, but especially in its film daddy, the original Khan-as-villain movie "Star Trek II: The Wrath of Khan." While the new film takes quite a few detours, it is full of homages to the earlier work.
Let's look back to 1982. "Star Trek: The Motion Picture" had been released in 1979 and faced a poor critical reception. Paramount, the film's studio, was gun-shy after the movie nearly doubled its original budget, ending up with a $46 million price tag. Nonetheless, plans for a second movie plodded along.
It's 30, 40 years later and we have new audiences. You can't keep dwelling on the old guys and the old things. It has…

The Windows 8 Start screen is a good starting point for Windows 8 devices with touch screens, but on PCs with standard screens, you might prefer to boot directly to the desktop. Previously, you could bypass the Windows 8 Start screen with Start8, but Windows 8.1 now lets you do it natively. Here's how:
Step 1: Right-click on the Windows 8.1 taskbar, then choose Properties.
Step 2: Click on the Navigation tab, then under the Start screen section, check the box next to "Go to the desktop instead of Start when I sign in."

The next time you boot Windows 8.1, you'll go straight to the desktop without ever seeing the Start screen.

Roku's speedy streamer is the best box yetThe good:The Roku 3's excellent new interface and faster processor makes it feel quicker and more responsive than any other streaming box. More than 750 channels are supported, including Netflix, Amazon Instant, HBO Go, Hulu Plus, Pandora, MLB.TV, Amazon Cloud Player, and Vudu. It also has cross-platform search that scours several major TV and movie services to find content. And Roku's nifty new remote has a built-in headphone jack that lets you listen without disturbing others. The bad:There's still no official YouTube channel. Some services have an outdated interface on Roku compared to other streamers. The Apple TV still works better within the Apple ecosystem. And the Roku 3 isn't a great option if you're mostly looking to stream your personal digital media collection. The bottom line:The Roku 3 is the best streaming-video box yet, with tons of content sources, lightning-fast performance, and an innovative remote wit…
